Abstract

本发明主要提供一种寻呼方法及系统，以解决现有技术中由于用户的移动性，返回的寻呼响应为目的MSC下的CELL ID，MME和IWS基于新的CELL ID选择到目的MSC，导致呼叫接续失败的问题。通过本发明，MME和IWS在接收寻呼请求时，就保存发送消息的MSC，在返回寻呼响应时原路返回。呼叫接续过程中，通过MSC之间局间切换流程，让用户切换到目的MSC下的目的BSC。从而可以提高语音终呼成功率。

Description

一种寻呼方法及系统 技术领域
本发明涉及移动通讯领域，特别是涉及一种寻呼方法及系统。
背景技术
LTE(Long Term Evolution，长期演进)是由3GPP(The 3rd Generation Partnership Project，第三代合作伙伴计划)组织制定的UMTS(Universal Mobile Telecommunications System，通用移动通信系统)技术标准的长期演进。图1是根据相关技术的LTE网络回落到CDMA(Code Division Multiple Access，码分多址)2000网络架构图，如图1所示，其中包含了如下网元：
E-RAN(Evolved RAN)：演进的无线接入网，可以提供更高的上下行速率，更低的传输延迟和更加可靠的无线传输。E-RAN中包含的网元是eNodeB(Evolved NodeB)，为终端的接入提供无线资源。
MME(Mobility Management Entity，移动管理实体)：控制面功能实体，临时存储用户数据的服务器，负责管理和存储UE上下文(比如UE/用户标识，移动性管理状态，用户安全参数等)，为用户分配临时标识，当UE驻扎在该跟踪区域或者该网络时负责对该用户进行鉴权；处理MME和UE之间的所有非接入层消息；触发在SAE的寻呼。
Serving GW(Gateway)：服务网关，该网关是一个用户面实体，负责用户面数据路由处理，终结处于空闲状态的UE的下行数据。管理和存储UE的SAE承载(bearer)上下文，比如IP承载业务参数和网络内部路由信息等。是3GPP系统内部用户面的锚点，一个用户在一个时刻只能有一个Serving GW；
IWS(Interworking Solution)：互操作节点。LTE覆盖下的终端不能处理语音业务时，可以先回退到电路域网络，在电路域网络处理语音业务。IWS负责实现LTE下的MME和电路域的MSC的交互。
CDMA20001X接入网：主要包括MS移动终端和BTS基站收发信机。基站收发信机负责无线信号收发，实现无线网络系统和移动台之间的通信。
BSC(Base Station Control)：基站控制器。负责BTS控制和管理，资源分配，无线连接建立，移动性管理，功率控制等。
MSC(Mobile Switch Center)：移动交换中心。负责呼叫建立，路由选择，呼叫控制，无线资源分配，移动性管理，位置等级，交换区内信道切换等。
IWS网元完成MME与MSC网元的互通，IWS与MME之间采用S102接口UDP隧道。
当用户被呼叫时，MSC通过IWS和MME网元对用户发起寻呼，如果此时用户 正好移动到目的MSC覆盖区域，用户返回寻呼响应时其中消息携带为目的MSC的CELL ID(小区标识码Cell Identification)，MME和IWS将基于新的CELL ID选择到目的MSC，导致呼叫接续失败。
图2是根据相关技术的1xCSFB(Circuit Switched Fallback，电路域回落)寻呼改进前呼叫失败的流程图，如图2所示，该流程包括：
步骤201，对用户发起呼叫，MSC发送寻呼请求消息给IWS网元；
步骤202，IWS接收到寻呼请求后，没有保存请求的MSC局向；
步骤203，IWS发送寻呼请求到MME；
步骤204，MME也不会保存发送请求的IWS IP地址；
步骤205，MME发起寻呼请求到UE；
步骤206，用户接收到寻呼请求后，返回寻呼响应；
步骤207，用户寻呼响应中携带新MSC下的CELL ID；
步骤208，MME收到UE寻呼响应，基于其中新的CELL ID查找到一个新的IWS，回寻呼响应给新IWS；
步骤209，新IWS收到寻呼响应，再次根据响应中的CELL ID选择新MSC；
步骤210，新IWS发寻呼响应到新MSC，新MSC收到后无法处理；
步骤211，发送寻呼请求的MSC等待寻呼响应超时，呼叫失败。
由于用户的移动性，返回的寻呼响应为目的MSC下的CELL ID，MME和IWS基于新的CELL ID选择到目的MSC，导致呼叫接续失败。
针对该问题，目前尚未提出有效的解决方案。
发明内容
